摘要建立了一套可精确测量低浓度NO2的傅里叶变换红外光谱系统(Fourier transform infrared spectrometer, FTIR)。运用该系统测量动态稀释法得到的不同浓度的标准气体中的NO2的浓度,显示出该系统具有良好的线性响应, 并以此建立了该系统的校准方程。比对试验证明了该系统的测量结果准确可靠; 稳定性研究则显示该系统具有良好的长期稳定性。

Abstract：A FTIR system for the accurate measurement of low concentration NO₂ was developed. By using the proposed syestem, the concentration of NO₂ in the different standard gas were measured; the standard gas were obtained by dynamic dilution method. It was indicated that the system has a good linear response, thus the calibration equation of the system was established. The comparison test showed that the system is accurate and reliable. The stability study showed that the system has good long-term stability. By using dynamic dilution method based on mass flow controllers, the standard gases with different concentration were obtained. This system has a calibration curve with good linearity. The comparison test shows that the system is accurate and reliable. The stability study shows that the system has good long-term stability.

Key words： metrology NO₂ monitoring FTIR dynamic dilution method standard gas
